Selecting Action | |
1.Hammering with rotation. | Hammering with rotation |
(5317-59/59A only) Use this | (5317-59/59A only) |
setting for drilling holes with | |
drill bits. | |
2.Hammering only. For use with | |
“hammering-only” accessories. | |
Use this setting for chiseling or | |
setting self-drilling anchors. | Hammering only |
3.Chisel adjustment. Use this | |
setting to adjust the angle of | |
the chisel blade in relation to the | |
tool. With a chisel mounted in | |
the tool: | |
• turn the knob to this setting | |
• rotate the chisel to the desired | |
angle | |
• turn the knob to "hammering- | |
only". | |
NOTE: To engage the hammering | |
mechanism, maintain pressure on | Chisel adjustment |
the bit. When the pressure on the |
bit is released, the hammering will stop.
Starting and Stopping
1.To start the tool, grasp the handle firmly and pull the trigger.
2.To stop the tool, release the trigger. Make sure the tool comes to a complete stop before laying the tool down.
Lock-On (5347-59/59A/59B)
The lock-on button holds the trigger in the ON posi- tion for continuous full speed use.
1.To lock the trigger, hold in the lock button while pulling the trigger. Release the trigger.
2.To unlock the trigger, pull the trigger and release. The lock button will pop out.
Operating
clutch prevents the bit from turning. If this occurs, stop the tool, free the bit and begin again.
Cold Starting
If this tool is stored for a long period of time or at cold temperatures, it may not hammer initially because the lubrication has become stiff. To warm up the tool:
1.Insert and lock a bit or chisel into the tool.
2.Pull the trigger and apply force to the bit or chisel against a concrete or wood surface for a few seconds. Release the trigger
3.Repeat until the tool starts hammering. The colder the tool is, the longer it will take to warm up.
Using Rotary Percussion Core Bits (5317-59/59A only)
Core Bits are useful for drilling large or long holes in concrete. MILWAUKEE Heavy-Duty Core Bits have heat-treated steel bodies with durable carbide tips. These core bits are specially designed for fast, accurate drilling with combined hammering and rotary action.
1.Clean and lubricate the threads on the adapter and core bit to make later removal easier. Thread the adapter shank to the rear of the core bit.
2.Push the guide plate
onto the pointed end 
of the center pin. Insert
the center pin and guide plate assembly into the core bit. Be sure the small end of the center pin is securely placed into the hole in the cen- ter of the core bit.
For LHS systems,
screw the threaded end of the centering bit into the core bit.
NOTE: If using an extension, first thread the adapter shank to the extension. Then thread the core bit to the extension.
3.Insert the adapter into the nose of the tool as described in “Installing Bits and Chisels”. Set the knob to the "hammering with rotation" setting.
5099 threaded stud is |
used, or a center pin |
and guide plate are |
not available, use a |
template or notched |
board to start the hole. |
5.Start the tool.After drilling |
to about the depth of the |
core bit teeth, remove |
the center pin and guide |
plate from the core bit |
(not necesary for LHS |
system). Resume drill- |
ing. |
6.To change the core bit, |
hold the tool upwards, |
pointing it away from |
your body, and run it |
briefly in forward to loos- |
en the core bit from the |
adapter. |
NOTE: To make deeper holes, remove the core bit, break and remove the core, then resume drilling. When drilling long or deep holes, after each inch of penetration pull the bit partially out of the hole while the tool is running, to help clear dust from the bit flutes. Dust can clog the bit flutes and can make the bit bind in the hole. If this occurs, stop the tool, free the bit and begin again.
Drilling Large Diameter Holes with Core Bits (5317-59/59A only)
When drilling holes with large diameter core bits, dust may build up in the cut and can cause the tool to stall, bind, or cut slowly. By creating an opening for the dust to escape, drilling time, bit stress, and tool stress can be reduced.
1.Start the cut as normal.
2.Once the bit is firmly established in the cut (about 1/4" deep),
remove the bit from the cut.
3.Remove the bit from the tool.
4.Install a standard fluted bit, ap- proximately 7/8" in diameter, onto the tool.
5.Drill a perpendicular hole through the kerf of the large hole.
• Depending on the location of the work, the hole should either break through the other side of the hole/floor or extend 4"-5" past the end of the workpiece (such as into the dirt below a concrete slab).
NOTE: If unable to drill a hole in the kerf, pull back on the bit with the hammer running. This will remove some of the dust and debris from the cut. Repeat this for every inch of drilling. If necessary, vacuum dust and debris from the cut and surrounding area.
7.For core bits, once the maximum core bit depth is drilled, the core must be broken and removed.
•Install a chisel bit.
•Place the chisel into the hole kerf.
•Chisel down into the kerf at several points until the core is loose or broken.
•Remove the core and vacuum/remove any remaining dust and debris.
•Install the core bit and continue the cut.
